Abstract (en)

The invention relates to a laundry treatment apparatus, in particular a dryer or washing machine having drying function, comprising: a laundry storing chamber for treating laundry using process air (A), a process air loop for circulating the process air through the laundry storing chamber, a process air heat exchanger (26a) arranged at or in the process air loop, and a heat pump system for dehumidifying and heating the process air, the heat pump system having a refrigerant loop comprising: a first heat exchanger (10) for heating a refrigerant and cooling the process air (A), a second heat exchanger (12) for cooling the refrigerant and heating the process air, a refrigerant expansion device arranged in the refrigerant loop between the second heat exchanger (12) and the first heat exchanger (10), and a compressor arranged in the refrigerant loop between the first heat exchanger (10) and the second heat exchanger (12), wherein the process air loop comprises a comprises a process air channel, the process air channel comprising a channel section unit (20d) for deflecting the process air (A) coming from the laundry storing chamber from a vertically downward or an inclined vertical downward direction to a horizontal direction towards the first heat exchanger (10). According to the invention the process air heat exchanger (26a) is at least partially integrated in or is part of said channel section unit (20d) that is deflecting the process air (A), and/or at least a portion or a substantial portion of a heat exchanging interface surface of the process air heat exchanger (26a) is forming a wall portion defining an outer wall section of the process air channel.
